3 Claims.

This invention relates primarily to a backguard assembly and lamp therefor which is particularly adapted for use with domestic ranges.

The main object of the invention is to provide a backguard assembly and lamp for gas ranges which is simple in construction, neat and attractive in appearance and well adapted for production at comparatively low cost.

Another object of the invention is to provide a combination back plate and lamp assembly for ranges of the character described having simple and effective means for securing the lamp shade to the back pl te in such a manner that it can be readily removed and which has simple and efiective fastening means for securing the shade in place.

A still further object of the invention is to provide a back plate and lighting fixture for ranges, which includes a lamp shade which extends over the front of the back plate and above the top thereof and which cooperates with the back plate to provide a lighting fixture which is neat and attractive in appearance and which at the same time will aiford sufficient light for normal operation of the range.

Further and more limited objects of the invention will appear as the description proceeds and by reference to the accompanying drawings in which Fig. 1 is a fragmentary view in front ele- 30 vation showing a gas range having my improved backguard and lighting fixture applied thereto;

Fig. 2 is a fragmentary view in end elevation; Fig. 3 is a detail view partly in section and partly in elevation with parts broken away to more clearly disclose the manner of securing the shade and lighting fixture in place; Fig. 4 is a vertical sectional view on the line 4-4 of Fig. 3; Fig. 5 is a detail view partly in section and partly in elevation disclosing a modified form of my in- 40 vention; Fig. 6 is a horizontal sectional view on the line 6-6 of Fig. 5; Fig. 7 is a vertical sectional view on the line of Fig. 5; and Fig. 8 is a detail view partly in elevation and partly in section more clearly disclosing the manner of securing the back plate in place.

Referring now to the drawings, the reference character I designates generally a gas range having a flat top 2. Disposed at the rear of the range is the backguard which is indicated by the reference character 3 and which has a horizontally disposed portion 4 and a vertically disposed portion 5. The backguard extends entirely across the back of the range, as shown in Fig. 1, and has its upper edge curved rearwardly as shown at 6. Disposed centrally of the back plate and adjacent the upper edge thereof is the lamp shade whichis indicated by the reference character 'l and which is of the shape shown most clearly in Figs. 1, 2 and 4. The lamp shade has a horizontally extending portion and a vertically extending portion which cooperates with the back plate to form a light chamber. The back plate is provided with an opening 8 which is disposed behind and opposite the lamp shade.

Carried by the back plate is a lamp socket 9 which is supported by a suitable bracket l0 spot welded or otherwise secured to the back plate and which'is adapted to receive therein a lamp bulb H which is disposed behind the opening 8. Extending over the lamp bulb is a closure l2 which is preferably forni'ed of sheet metal and secured to the overturned portion of the back plate by means of bolts l3 and nuts M. Also secured to the overturned portion of the back plate is a plate l5 whichis shaped in section, as shown most clearly in Fig. 4 and which also is held in place by the bolts l3 and nuts Hi The plate l5 has an overturned flange portion l6 which engages with a flange or bead ll formed on the top edge of the shade 1 and which serves to secure the shade in place. The plate I5 is also provided with a pair of projections which are indicated by the reference characters l8 and I9 which extend within the shade and serve to prevent endwise movement thereof. In order to remove the shade, it is merely necessary to lift it upwardly from the position shown in Fig. 4 until the bead ll disengages the flange l6 whereupon the shade may be entirely removed from the back plate. Carried by the back plate is the switch 20 which has a switch lever 2| that extends through the curved portion of the back plate so as to be readily accessible. The reference characters 22, 23 and 24 designate the electrical connections for the lamp which also connect with the switch.

In Figs. 5 to 8, inclusive there is disclosed a slightly modified form of my invention. .The reference character 3 designates the backguard which has a vertically disposed front portion 5 to which the lamp assembly is secured. The top of the backguard 3 has its upper ,edge curved over rearwardly as shown at 6. The backguard also has an opening 8 therein over which the shade 1 is secured. The backguard and shade are identical with the backguard and shade disclosed in Figs. 1 to 4 inclusive. Carried by the back plate is a closure member 25 which is preferably formed of sheet metal and is rectangular in section as shown in Fig. 6. The front edge of the member 25 has a flange 26 thereon which engages 4 wise movement.

the lower edge of the opening 8 in the backguard. The top of the closure member 25 is turned inwardlyasv shown at 21 and is secured to. the turned over top portion of the backguard by means of bolts 28 and 29. Secured to the member 25 is a plate 30 which has an overhanging flange portion 3| which engages with the flange I] provided on the shade 1. justably secured in place by means of a pair of bolts 32 and 33 which engage in elongated slots provided in the plate 30. Disposed behind the opening l8 and within the enclosure provided by the member 25 is a lamp socket 34 which receives therein a lamp bulb 35. The socket is secured to the member 25 by means of a bolt 36 and a nut 31. Leading from the lamp socket are wires 39 and 40. The wire 39 leads to a switch 4| carried by the overhanging top portion of the backguard. Leading from the switch is a wire 42 which connects with a suitable source of current. The switch lever 4|- projects through the overhanging top portion of the backguard adjacent the lamp. The plate 30 is turned downwardly at the opposite edges thereof as shown at 43 and 44 so as to hold the shade against endit is merely necessary to lift it upwardly from the position shown in Fig. 7 until the flange l1 disengages the flange 3| on the plate 30 whereupon the shade may be entirely removed from the backguard. In other respects this form of the invention is identical with that shown in Figs. 1 to 4 inclusive.

It will now be clear that I have provided a backguard assembly and lighting fixture for ranges which will accomplish the objects of the invention hereinbefore stated. It will be seen that the shade and lamp assembly are secured in place entirely by the plate l5 which engages with the be ad on the upper edge of the lamp shade and that the lamp shade is readily removable to provide access to the lighting fixture for the purpose of replacing the lamp bulb. The entire backguard and light assembly are formed of a minimum number of parts which are well adapted for production at very low cost.

It is of course to be understood that the embodiment of the invention herein disclosed is merely illustrative and is not to be considered in a limiting sense as various changes may be made in the details of construction and the arrangement of The plate 30 is ad- In order to remove the shade parts without departing from the spirit of my invention as the invention is only limited in accordance with the scope of the appended claims.

Having thus described my invention, what I claim is: Y

1. The combination with a range provided with a back plate having a vertically disposed front wall and a rearwardly extending top portion, a lamp shade pivotally supported on said top portion and engaging said front wall and cooperating therewith to form a light chamber, means carried by said back plate having an overhanging flange thereon, said shade having a flange thereon engaging said overhanging flange for holding said shade in place, the center of gravity of said shade being disposed below its point of support whereby the weight of said shade tends to hold said flanges in engagement.

2. The combination with a range provided with a back plate having a front wall and a rearwardly extending top portion, a member secured to said back plate and having an overhanging flange disposed above said top portion, a lamp shade resting onsaid rearwardly extending portion and having a flange thereon engaging with said overhanging flange, said shade having a downwardly extending portion engaging with the front portion of said back plate and cooperating therewith to form a light chamber, the center of gravity of said lamp shade being disposed below its point of support whereby the weight of said shade tends to hold said flanges in engagement by gravity, and a lamp for illuminating said chamber. 3. The combination with a range provided with a back plate having a vertically disposed front portion and a rearwardly curved top portion, a lamp shade pivotally supported on said rearwardly curved top portion and having a flange at the top thereof, said shade having a downwardly extending portion cooperating with the front portion of said back plate to provide a light chamber, a plate carried by said back plate and having an overhanging flange engaging the flange on said shade, the center of gravity of said lamp shade being disposed below its point of support so that the weight thereof tends to hold said lamp shade in place, the upward pivotal movement of said lamp shade about its point of support serving to disengage said flanges to permit removal of said shade.
